Drivin cross country, lets hope I make it...
Started driving across country a few days ago (RI to Los Angeles), and somewhere in VA I noticed the jeep (01 TJ) was pushing a lot of coolant, with vigorous bubbling in the coolant overflow reservoir. Seems to only happen when it's very hot out. My first guess was the thermostat or head gasket. I replaced the thermo last year.
There also seems to be what can only be engine coolant leaking out of one of the ac pressure ports (the one right above the thermostat). If I unscrew the cap of that ac port i can see coolant and gas slowly bubbeling out.
I normally don't use my ac, by I've got a 5 month old puppy with me, so the ac is crucial.
I had it recharged before I left, and they said I do likely have an ac leak somewhere since it was so low. They didn't put in a sealer with the recharge but I'm carrying a couple cans of sealer and freon with me.
Is it possible somehow to have engine coolant leak through into the ac? I thought they were isolated systems..
I do all my own maintenance, but when it comes to the ac I'm lost.
